ive heard that whats in the hatch somehow explains the numbers. Even if not strait away. And also if you use the numbers in longitude and latitude on a map its shows up as like Africa. which is supposedly around where the plane went down. between Australia and America.
This pic is what happens when you put the numbers in order on latitude and longitude
latitude- 4.815
longitude- 16.2342
Also works if you switch the numbers between latitude and longitude
try it yourself
